Objective:To observe the effects of isokinetic muscle strength training at different angular velocities on knee hyperextension in patients after stroke,and to find out better angular velocity.Method:Eighty patients with knee hyperextension after stroke were randomly divided into four groups:the control group,30°/s group,60°/s group and 90°/s group,20 cases in each group.The control group received only routine rehabilitation treatment,and the other three groups received an additional 30°/s,60°/s or 90°/s isokinetic knee flexion/extension training besides the routine treatment,respectively.Before and 3 weeks after treatment,peak torque(PT),peak torque to body weight ratio(PT/BW),average electromyographic(AEMG)and integrated electromyographic(iEMG)of the extensor and flexor knee muscles,the effective rate of knee hyperextension and lower limb Fugl-Meyer motor function score(FMA)were measured.Result:Before treatment,there was no significant difference among the four groups(P>0.05).After 3 weeks treatment,PT,PT/BW,AEMG,iEMG of the extensor and flexor knee muscles and FMA in four groups were significantly improved as compared with those before treatment(P<0.01).Moreover,the improvement of evaluation results in the 30°/s group,60°/s group and 90°/s group were higher than those in the control group(P<0.05),and those in the 30°/s group and 60°/s group were higher than those in the 90°/s group(P<0.05).However,no significant difference was found between 30°/s group and 60°/s group(P>0.05).In addition,the effective rate of knee hyperextension in the 30°/s group or 60°/s group(85%)was significantly higher than that in the control group(40%)(P<0.05),but there was no significant difference between the 90°/s group and the control group(P>0.05).Conclusion:Isokinetic muscle strength training at different angular velocities can increase the muscle strength of knee flexors and extensors,improve the control ability of knee joint,and better improve knee hyperexten-sion in patients after stroke.The lower angular velocity(≤60°/s)has a better effect.

Objective To observe the clinical effect of peripheral facial paralysis treated by the external stylomastoid foramen and acupoint injection of Mecobalamin combined with acupuncture. Methods 144 cases of patients selected were randomly divided into three groups: group A( the acupuncture combined with electric acupuncture) ,group B(the external stylomastoid foramen and acupoint injection of Vitamin B_(12) combined with acupuncture) ,and group C( the external stylomastoid foramen and acupoint injection of Mecobalamin combined with acupuncture). After A two - month treatment course,the subjective examination and scale assessment were carried out. Results The healing time was (42.47 +6.29) days in group A with (37.41 +4.18) days in group B and (26.78 +2.66) days in group C. After A two - month treatment course,the obvious effective rate was 81.84% in group A with 89.76% in group B and 97.86% in group C. Conclusion Three kinds of treatment methods are all effective against the third and the fourth grade of peripheral facial paralysis. Mecobalamin injection combined with acupuncture group can shorten the course evidently.
